    Getting creative to cut methane from cows

    View the video

    In a pasture outside Edmonton, Canada, you’ll find a few dozen cows doing what cows do: mostly eating. The average animal spends eight-plus hours a day filling its belly, or as is the case with cows, bellies. Along with that enormous appetite, cows are born with the ability to digest almost any plant they can chew, thanks to a multichambered stomach and a helpful army of...

    That's One Weird Tooth

    What Martin Nweeia noticed first when he encountered narwhals, he says, was the sound. In May 2000, as spring was just reaching Baffin Island in the Canadian Arctic, a famed local hunter took Nweeia out on the ice searching the open water for those tusk-bearing, high-Arctic whales. "I was sitting on a bucket out on the ice doing polar bear watch," he says. At that time of year, daylight lasts...

    Fish Din: Reef clamor attracts young fish settlers

    When it comes to real estate on a coral reef, young fish may be looking for noise, noise, noise.

    Most reef fish spend the first stage of their lives as specks in open water away from any reef. Just how these fish larvae, which resemble crumb-size shrimp, end up on a reef as adults has long intrigued biologists and conservationists.

    Now, an experiment using artificial reefs...

    Infrasonic Symphony

    "Let me start off with a riddle," says NASA scientist Allan J. Zuckerwar. In his office in Hampton, Va., he rattles off items as dissimilar as rhinoceroses, supersonic aircraft, and hurricanes. "Now, what do they have in common?" The answer, Zuckerwar explains, is that each one generates silent infrasound—long sound waves at a frequency below 20 hertz. People can't hear anything below that...

    Calling All Cows

    Last May, tissues from the carcass of a North American cow turned up positive for bovine spongiform encephalopathy–the ailment responsible for mad cow disease. Within hours, the Canadian government traced the animal to the Alberta farm where it had been raised for its 8 years of life. In short order, other members of its herd were quarantined.

    What made this...
